Spam Blocker giving very high spam ratings after re-subscribing

As it says in the title, the Spam Blocker app started going crazy with its rating system right after we re-subscribed for another year. The app hadn't expired, and still had 5 days left on the previous year's subscription.

I know it makes no sense, but that's literally the only thing that changed.

I've had to lower the spam threshold to "5", and it's still catching and quarantining a lot of legitimate email that it wasn't before.

The app does seem to be getting nightly updates with no issues. I just can't explain why it suddenly went into overdrive like this.
